[Bug middle-end/31497] FAIL: gcc.dg/builtins-59.c on PA HP-UX

I guess so.  All the testcases rely on either availability of cexp() or
sincos().
For the former via TARGET_C99_FUNCTIONS, for the latter via TARGET_HAS_SINCOS.

But it is interesting that -59 fails, as the transformation checked should
be done via fold_builtin_sincos which only bails out if !TARGET_C99_FUNCTIONS
or cepxi is not available (but that is a GCC builtin, so should be available
all the times).

I don't have time to investigate if we can somehow relax all the machinery
around this transformation, but we basically try to avoid locking us up
in a corner where we end up with the internal CEXPI but have no way
to re-emit either sincos or cexp calls.
